A data architect needs to design a solution for ingesting, storing, and analyzing large volumes of data from multiple sources with both batch and real-time processing capabilities. Which Azure service provides this unified analytics platform?
Answer: Azure Synapse Analytics
Azure Synapse Analytics is a unified analytics platform that integrates big data and data warehousing with both batch processing and real-time analytics in a single service.
An architect must design a solution where Azure Cosmos DB consistency needs to balance between strong consistency for reads and high write throughput globally. Which consistency level provides linearizability with lowest write latency tradeoff?
Answer: Bounded Staleness
Bounded Staleness guarantees reads lag writes by at most K versions or T time interval, providing strong ordering guarantees with better write throughput than Strong consistency.
A company needs to implement a hot path and cold path architecture (lambda architecture) for IoT data on Azure. Which combination of services best represents this pattern?
Answer: Event Hubs + Stream Analytics (hot) and Data Factory + Synapse (cold)
Event Hubs with Stream Analytics handles the real-time hot path while Data Factory with Synapse Analytics processes historical batch data in the cold path of a lambda architecture.
An architect needs to choose between Azure Blob Storage and Azure Files for a scenario where multiple Azure VMs running Windows need to access a shared file system via SMB protocol. Which service is appropriate?
Answer: Azure Files
Azure Files provides fully managed file shares accessible via SMB and NFS protocols, suitable for shared file system access across multiple Azure VMs.
A company wants to implement geo-redundant storage for their Azure SQL Database to ensure data is replicated to a paired region for disaster recovery with an RPO of less than 5 seconds. Which feature should be configured?
Answer: Azure SQL Database active geo-replication
Azure SQL Database active geo-replication creates up to 4 readable secondary replicas in paired or other regions with asynchronous replication achieving RPO typically under 5 seconds.
An architect is designing a document storage solution for an application that requires schema flexibility, rich queries with indexing on all fields, and horizontal scaling. Which Azure NoSQL service best fits this requirement?
Answer: Azure Cosmos DB for NoSQL (SQL API)
Azure Cosmos DB for NoSQL (SQL API) provides schema-less document storage with automatic indexing on all fields and rich SQL query capabilities with global scaling.
